Short answer: the FlipEars Aisha Electri. It ranks #173 of 450 in-ear headphones by sound quality, rated 4.3/5, at $699; the SoftEars RSV ranks #184, rated 4.2/5, and costs $729, so there is little reason to consider the other one.
The case for the SoftEars RSV: Its preference score of 76 from crinacle’s measurement comes with just 1.76 dB of deviation, so tonal balance is smooth and natural. The catch: Presence runs about 2.9 dB below target, giving vocals and guitars a slightly laid back edge, and a 4 dB dip near 10.3 kHz trims some sparkle.
Buy the FlipEars Aisha Electri. It is rated higher for sound quality than the SoftEars RSV and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

SoftEars RSV: $729.00 Amazon eBay
Pros: Its preference score of 76 from crinacle’s measurement comes with just 1.76 dB of deviation, so tonal balance is smooth and natural. Across 21 hobbyist measurements on squig.link no band strays more than about 3 dB from target, and sub-bass stays within 6 dB down to 20 Hz. It is rated above the SoftEars Twilight, which costs more, and its 125 dB/Vrms sensitivity makes it easy to drive from a phone.
Cons: Presence runs about 2.9 dB below target, giving vocals and guitars a slightly laid back edge, and a 4 dB dip near 10.3 kHz trims some sparkle. The 8 ohm impedance is very low, so it pairs best with sources that have low output impedance to keep its tuning intact.
